This paper introduces the system of measuring the same state of temperature based on multisensor. Multisensor is connected with host computer through DUT series data acquisition module and RS485 to RS232 convertor. Comparing with the result of single sensor, more accurate estimation of temperature state is achieved by processing the data of multisensor based on data fusion.

【期刊论文】VARIANCE ESTIMATION IN MULTISENSOR FUSION ALGORITHM

Abstract: In weighted fusion algorithm for multisensor, the weights are only determined by noise variance and the precision of the variance estimation will affect the performance of the fusion algorithm. An approach of variance estimation for multisensor is presented and proves unbiased in this paper. The recurrence formula for the algorithm is also proposed, and moreover, there is no need for initial values, for which the approach is adaptive and can be used in real-time estimation. A numerical example is given to show the usefulness of the approach. Copyright
